Exploring the Effectiveness of Ajwain Cream in Treating Taxane-induced Peripheral Neuropathy in Cancer Patients: A Pilot, Randomised and Double-blind Clinical Trial

Chemotherapy-induced peripheral neuropathy is a common disorder among cancer patients receiving various chemotherapeutic protocols. The present study aimed to explore the feasibility of ajwain (Trachyspermum ammi [L.] Sprague) cream in treating peripheral neuropathy symptoms triggered by taxane chemotherapeutic agents. This was a pilot, double-blind, and randomised clinical trial on patients with peripheral neuropathy attributable to chemotherapy with taxane drugs during 2021–2022 in Tehran. Patients received ajwain or placebo cream for four weeks and filled out the chemotherapy-induced peripheral neuropathy assessment tool (CIPNAT) at the start and end finale of the trial. Side effects were also noted. Thirty patients suffering from breast, lung, gastro-intestinal, or prostate cancer were allocated to each of the drug and placebo groups. The mean difference in CIPNAT score between the groups was 0.83, demonstrating the statistical ineffectiveness of the drug compared with the placebo (P = 0.372). The safety profile showed promising outcomes at the end of the trial. Although the effectiveness of ajwain cream was unacceptable in treating chemotherapy-induced peripheral neuropathy symptoms, multicentre controlled trials with ample sample size are mandatory for an all-inclusive inference.
